• #0: an immediate value to be used by the operation
• Rd: destination register
• Rm: register that contains the first operande
• Rn: register that contains the second operande (also destination register when 'Rdn')

Branch

• cannot be omitted !
• imm32 = SignExtend(imm8:'0', 32)
• imm32 is the Program Counter value of the label in the program. imm8 must be encoded to set the correct value for imm32.
